Xebia Web Framework Contest

What's the best Web Framework for developing RIA applications?

That's the question people at Xebia France tried to answer through their contest

Competitors were:

• Flex 3
  
• Silverlight beta 2
  
• Google GWT
  
• Echo 3
• Java FX

The clear winner was Flex 3. It's worth noting that at the moment Java FX is still immature.
